Glioblastoma multiforme (GBM) is the most common malignant brain tumour in adults. The poor prognosis and short median overall survival of patients with GBM associated resistance to therapy after surgical adjuvant treatment. expression various acetylcholine receptors (AChR) has been widely reported. present study aimed investigate cholinergic system‑related genes primary explore antiproliferati...

BACKGROUND Resistance to chemotherapy is a growing concern, thus natural anticancer agents are drawing the attention of many scientists and clinicians. One natural anticancer agent, umbelliprenin, is a coumarin produced by many species of Ferula. OBJECTIVES We aimed to examine the inhibitory effect of umbelliprenin on human and mouse bone marrow-derived stem cells (BMDSCs), peripheral blood m...

BACKGROUND Toll-like receptor 3 (TLR3) recognizes double-stranded RNA (dsRNA) and induces inflammation. In this study we attempted to ascertain if there are endogenous host molecules controlling the production of cytokines and chemokines. Two candidates, ribosomal protein L19 and L22, were analyzed to determine if they influence cytokine production followed by TLR3 activation. In this study we ...

OBJECT The goal in this study was to investigate the antitumor effect of aspirin in glioblastoma cells and the molecular mechanism involved in its antineoplastic activities. METHODS The authors used the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method, flow cytometry, the annexin V method, and Transwell cell invasion test to detect the proliferation and invasive activity of...

The platelet-derived growth factor (PDGF) A-chain gene is expressed in a tissue- and developmental stage-specific manner. Here we identify an S1 nuclease sensitive region within the first intron that functions as a negative regulatory element in HeLa but not in human glioblastoma (A172) cells in transient transfection assays. A 147 bp DNA fragment that contains this element functions in a posit...

Chlorotoxin is a 36-amino acid peptide derived from Leiurus quinquestriatus (scorpion) venom, which has been shown to inhibit low-conductance chloride channels in colonic epithelial cells. Chlorotoxin also binds to matrix metalloproteinase-2 and other proteins on glioma cell surfaces. Glioma cells are considered to require the activation of matrix metalloproteinase-2 during invasion and migrati...

UHRF2 is a member of the ubiquitin plant homeo domain RING finger family, which has been proven to be frequently up-regulated in colorectal cancer cells and play a role as an oncogene in breast cancer cells. However, the role of UHRF2 in glioma cells remains unclear. In this study, we performed real-time quantitative PCR on 32 pathologically confirmed glioma samples (grade I, 4 cases; grade II,...

Glioblastoma (GBM) is one of the most lethal forms of human cancer, and new clinical biomarkers and therapeutic targets are urgently required. microRNAs (miRNAs) are small, non-coding RNAs that negatively regulate gene expression at the post-transcriptional and/or translational level by binding the 3' untranslated regions (3' UTRs) of target mRNAs. The dysregulated expression of several miRNAs ...

Histone deacetylase inhibitors that increase histone acetylation on transformed cells are being investigated as unique anticancer drugs. The aim of this investigation was to evaluate an antiproliferative activity of the histone deacetylase inhibitors sodium butyrate (NaBT) and trichostatin A on 5 glioma cell lines, T98G, A172, U-87 MG, U-118 MG, and U-373 MG, with the examination of the altered...
